Specification of Letters Patent.

Patented Feb. 8, 192i.

Application filed September 4, 1917. Serial no. 139,444.

To all whom it may concern:

'Be it known that I, HENRY L. TIFFANY, a citizen of the United States,and a resident of South Dartmouth, in the county of Bristol and State ofMassachusetts, have invented an Improvement in WVinding and ShippingCones for Knitting and like Machines and Caps Therefor, of which thefollowing description, in connection with the accompanying drawings, isa specification, like characters on the drawings representing likeparts.

This invention relates to cones particularly adapted to have woundthereon yarn,

thread or the like of the commonly known cone winding form and fromwhich yarn or thread is drawn off axially or substantially so to theneedles of the knitting machine. 1 p

In order that the principle of the invention may readily be understood,I have disclosed a single embodiment thereof in the accompanyingdrawing, wherein Figure 1 is a side elevation of a winding or shippingcone embodying my invention; Fig. 2 is a vertical sectional vlew of theupper part of such cone upon an enlarged scale;

.Fig. 3 is a plan view of a cone having my invention applied thereto;and

Fig. 4 is a somewhat diagrammatic representation in section of adeformed tip end of a winding cone having a reinforcing member appliedthereto.

Cones adapted to receive or have" yarn or thread wound thereon and, fromwhich such yarn or thread is drawn oif axially when in upright positionto the needles of the knitting machine or for like purposes are commonlyformedof paper rolled in one or more layers or coils into conical form.

These cones are adapted to be mounted for winding upon tapering arborsof the general shape of'the cones and extending into the same to withinan inch or two of the tip end thereof. The ends of these cones protrudeover the complete yarn or thread mass.

For a great many years cones were made with a square or open tip end,-being of the so-called square nosed type. In the patent to Charles Gess,No. 986,379, dated March 7, 1911, is disclosed a winding and shippingcone having the apex end bent inward form,- ing an arch accomplishingimportant re-. sults. The said Gess cone has gone into very extended useand to a very large extent has supplanted the old square nosed cone.

The objectof my invention is to provide means whereby a cone ofthe'so-called Gess type, the efiiciency of which has been impaired byrepeated use, may be rendered perfectly serviceable for further use, andby which all the advantages of the Gess cone may be retained. To thisend I preferably provide a cap-like member, which may be of relativelythin but stout paper, thin sheet metal, celluloid or the like.Preferably, however, I employ paper. member may be molded into shape andmay thereafter be applied to the desired cone, or within the scope andpurpose ofmy in- .vention the paper or other material in an ceiving aheavy blowQ While the effect of such blows upon the tip end of the conevaries, and damaged cones therefore differ somewhat in shape at the tip,I have found that I may mold a paper or like cap member that can beapplied to a very large proportion of such damaged cones so as to fitreadlly thereon and render them entirely acceptable. I will describe,one form of my invention.

Referring more particularly to the drawi ing, the shipping and windingcone is indicated at 1, it being markedly tapering as set forth in thesaid Gess patent, and provided with a single superficial roughening 2.

The cap like The tip end 3 of the cone is inturned as disclosed in thesaid Gess patent, and the opening 4 in the said tip end may besubstantially or in fact entirely closed in the vint'urning process,since my invention is not limited in this respect.

Cones of the generalcharacter to which my invention pertains receive alarge package or mass of thread or yarn wound thereon in a comparativelyfew number of turns 01' coils in each traverse of the yarn or threadfrom end to end-of the cone. The cone-must therefore be of heavy, stiffpaper so as to support the large and heavy package of yarn or thread.Each wound package weighs 1% to 2 pounds and the wound cones are shippedin large wooden cases containing about 150 yarn packages. Intransportation the tip of the Gess or round nose cone withstands acrushing pressure far better than the square nose cone, but occasio'nally the tip of the round nose cone is .damaged or, what is morelikely, such tip becomes more or less. impaired in re-use'; In thosemills wherein winding and kn1tting are both carried on, it is a commonment, to sort out and classify such used cones, discarding the defectivecones, if any theta be, and to sell them to winding mills. Thus itcomes'about that the Gess or round nosed cone is repeatedly used andsuch 'damage as is received by the inturned tip end is more frequentlydue to such continued reuse than to blows or crushing pressure intransportation.

. In accordance with my invention l[ provide for quick and cheapapplication to such damaged round nosed or Gess cones of a cap likemember 5 conforming to the shape of the unimpaired tip end of the coneas indicated most clearly in Fig. 2 and having a sharply inturnedtipportion 6, which preferably is of just sufficient area and shape toconform to and fit snugly against the usual raw edge of the inturne'dtip end of the cone. Such raw edge is usually of a thicknesssubstantially corresponding to the thickness of paper or other materialof which the cone is made.

The cap 5 is intended to be secured to the tip end of the cone and forthis purpose I preferably use some suitable adhesive such as gum. Theguin or other adhesive should be applied to the entire inner surface ofthe cap, including the sharply inturned portion 6 so that such cap istightly secifred throughout its entire extent. Moreover, the material ofthe cap'is preferably so thin as to merge, as indicated at 7, with thesurface of the cone, which is preferably roughened and so that no ridgeis presented to the .unwinding yarn or thread. Such construction is moreor less diagrammatically indicated. in Fig. 2.

.My invention is not limited in this respect,

but preferably and for the best results 'no ridge should exist at thebase of the cap 5 or elsewhere. lif desired, the cone 1, before the caphas been. applied thereto, may be compressed ortreated so as to beslightly reduced in diameter and so as in efiect to form an annularshoulder for the receptlon of the lower edge of the cap 5, thusproviding for an absolutely smooth line .of junction between the loweredge of the cap and the cone.

The paper or other material of which the cap is or maybe formed ispreferably stiff the tip and this renders more difficult the application of a cap thereto or the retention of the cap in use, since thecone is apt to become battered or subjected to rough treatment in use inmills or transportation. In the case of a cone deformed in use, the tipthereof presents irregular depressions or pockets which receive andretain relatively large amounts of the adhesive which is applied to theinner surface of the cap. Thus I provide localized anchors that servemost, effectively to retain the cap in position.

So far as I am aware, I am the first to apply to a deformed or usedinturned end of a cone tip a member.

The cap or reinforcing member of my invention is not intended to beapplied to a new or perfect winding cone having an inturned end, but toa winding cone, the inturned end whereof has become deformed or impairedfrom any cause,'as approximately indicated at 8 on Fig. 4.

Having thus described one illustrative embodiment of my invention, Idesire it to be understood that although specific terms are employed,they are used in a generic or descriptive sense and not for purposes oflimitation, the scope of the invention being set forth in the followingclaims:

1. As an article of manufacture, a winding cone for knitting machinesand the like having a'roughened yarn retaining surface markedly conicalin shape to permit the yarn to free itself from the roughened surfacewhen drawn from the end of the cone and having an inturned tip enddeformed in use, thereby presenting irregular depressions, an appliedreinforcing cap-like member upon the outer surface of the tip end andrestor- .ing the original contour thereof and adhesive material betweensaid cap and the cone and received infthe said irregular depressions,thereby providing effective localized anchorings for the cap.

2. As an article of manufacture, a winding cone for knitting machinesand the like having a roughened yarn retaining surface markedly conicalin shape to permit the yarn to free itself from the roughened surfacewhen drawn from the end of the cone and having an inturned tip enddeformed-inv use, an appliedreinforcing cap-like member secured to saiddeformed tip end and substantially restoring the original contourthereof, and an adhesive lining the inner reinforcing preferablycap-like surface of the cap and received in excess quantities in thelocalized deformations of the ti 3 end of the cone.

3. s an article of manufacture, a winding cone for knitting machines andthe like having a roughened yarn-retaining surface markedly conical inshape to permit the yarn to free itself f'romthe roughened surface whendrawn from the end of the cone and having an inturned tip end deformedin use, thereby presenting irregular, spaced depressions, an appliedreinforcing cap-like member of thin, stout paper upon the outer surfaceof the deformed tip and restoring the original contour thereof, andadhesive material between said cap and the cone and receiving saidirregular, spaced depressions, thereby providing effective localizedanchorings for the cap.

4. As an article of manufacture, a winding cone for knitting machinesand the like having a roughened, yarn-retaining surface markedly conicalin shape to permit the yarn to free itself from the roughened surfacewhen drawn from the end of the cone and having an inturned tip enddeformed in use, thereby presenting irregular, spaced depressions, saidtip end having a small axial opening, the rim of which is composed ofthe raw edge of the cone material, and an applied reinforcing cap-likemember of thin, stout paper upon the outer surface of the tip andrestoring the original contour thereof, said cap having an inturned rimat its own tip which is co-extensive with and conforms to the said rawedge rim of the tip end of the cone, and adhesive material between saidcap and the cone and received in said irregular depressions, therebyproviding localized anchorings for the cap.

5. As an article of manufacture, a winding cone for knitting machinesand the, like formed of heavy paper rolled into shape and having amarkedly conical surface to permit the yarn to free itself when drawnfrom the end ofthe cone in use, the conical surface being roughenedthroughout the greater portion of the extent thereof, the tip of thecone being inturned and originally polished and smoothed, but deformedin use, thereby presenting irregular, spaced depressions, the said tipend having a small axial opening, the rim of which is composedof the rawedge of the cone material and an applied, reinforcing, cap-like memberof thin, stout paper upon the outer surface of the tip of the cone andrestoring the original inturned contour thereof, said cap having aninturned rim at. its own tip co extensive with andconforming to the rawedge rim of the tip end of the cone, and adhesive material between saidcap and the cone and received in said irregular depressions, therebyproviding localized anchoring for the cap, the lower edge of the capmerging with the surface of the cone face thereof; applying said memberto the tip of a winding cone originally inturned and originally polishedand smooth but deformed in use, thereby presenting irregular spacedformations; and securing the said.

member in place by the application of adhesive material between saidmember and the tip of the cone and received in said irregulardepressions, thereby providing localized anchorings for the said memberand causing the lower edge of said member to merge with the surface ofthe cone without presenting a ridge whereby a smooth unimpaired surfaceis presented to the unwinding yarn.

7. That method of restoring, strengthening'or renewing tips of windingcones for knitting machines that have been damaged in use and whichcones have a markedly conical butroughened surface permitting the yarnto free itself when drawn from the cone, consisting in providing acap-like member of thin, stout, paper-like material having a shaperendering it capable when applied to the outer surface of the tip of thedamaged winding cone for restoring the original surface thereof; saidmember having an inturned rim at its own tip substantially ooextensivewith and adapted to conform to edge of the cone tip material; andsecuring the said member in placeby the application of adhesive materialbetween said member and the tip of the cone and received in saidirregular depressions thereby providing 10- calized anchorings for saidmember and causing the lower edge of said member to merge with thesurface of the cone without presenting a ridge, whereby a smoothunimpaired surface is presented to the unwinding yarn.

In testimony whereof, I have signed my name to this specification.

HENRY L. TIFF ANY.
